ATTACHMENT FOR SPlNNING-MULES.

SPECIFICATION forming part of Letters Patent No. 785,470, dated March21, 1905.

Application filed April 2'7, 1904. Serial No. 205,086.

To all whom it may concern:

Be it known that we, JOHN BOND and LEVI H. BOND, citizens of the UnitedStates, and residents of Waterloo, in the county of Seneca and State ofNew York, have invented a new and Improved Attachment. for Spinning-Mules, of which the following is a full, clear, and exact description.

The invention relates to spinning; and its object is toprovide a new andimproved attachment for spinning-mules to securely lock the carriage inposition when stopped to prevent rebound of the carriage and imperfectformation of the yarn.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a sectional side elevation of the improvement as applied.Fig. 2 is an enlarged face view of the improvement, showing thecarriage-locking device in an inactive position. Fig. 3 is a sideelevation of the same. Fig. i is an enlarged face view of theimprovement, showing the carriage locked in place; and Fig. 5 is a sideelevation of the same.

The mule-carriage A, carrying the spindles, is mounted to travel onrails B and is caused to recede from the roving-drum and to traveltoward the same by the usual actuating mechanism on the head-stock C,and the changes in the travel of the carriage are automatically producedby the ordinary changing device such, for instance, as is shown inUnited States Patent N 0. 272,401, February 20, 1883, granted to E. A.Baldwin. In mules of this character when the lever E of thetravel-changing device, which is on the carriage, is thrown by theoperating-lever D to the right or in the position shown in Fig. 2 thesaid lever when the carriage approaches the head-stock operates upon theactuating mechanism thereof to cause the said mechanism to start thecarriage on its outward movement, so that when the lever is in thisposition the travel of the carriage is continuous. When, however, thelever E is thrown to the left or in the position shown in Fig. 4, thesaid lever does not operate the actuating mechanism, and consequentlythe said mechanism is rendered inactive and the carriage stops.

The carriage by its acquired momentum rebounds when stopped, and toprevent this rebound a locking device is provided to securely hold andlock the carriage A in place the moment it is stopped. By preventing therebound of the carriage a subsequent imperfect formation of the yarn isprevented, as the forcible rebound of the carriage tends to undulystretch the yarn, thus rendering the same weak or imperfect. The lockingdevice consists, essentially, of a hook F extending longitudinally underthe carriage A and fulcrumed at F to the carriage, as plainly indicatedin Fig. 1. The hook F is adapted to engage a keeper G, fixed to thefloor or to the frame of the head-stock C, so that when the carriage Areaches the end of its return stroke and is stopped the hook F is in alowermost position and engages the keeper G, and thereby locks thecarriage against rebounding. While the carriage A is i on its ordinarytravel toward and from the headstock the hook F is held in an uppermostposition, as shown in Figs. 1, 2, and 3, so that the head of the hookdoes not engage the keeper G, and consequently the locking device forthe carriage does not interfere with the latter as long as the carriageis traveling forward and backward during the spinning operation. Thehook F is, however, automatically swung downward to engage the keeper G,as previously described, whenever the lever D is thrown over to bringthe stopping device for the carriage A into action and the carriage hasbeen stopped, and for this purpose the free end of the hook F isconnected by a link H with a slide I, mounted to slide up and down insuitable bearings formed ona bracket J, attached to the carriage A, andon the upper end of the slide I is journaled a frictionroller I,normally resting on the top edge of the head K of a bar K, mounted toslide transversely in suitable bearings arranged on the bracket J. Thebar K is pivotally connected by a link L with the upper end of the leverE, secured at its lower end on the shaft E, onwhich the stopping-lever Dis secured. The free end of the head K of the bar K is provided with abevel K so that when the stopping-lever D is thrown over by the operatorand the lever E swings into the position shown in Fig. 4 to stop thecarriage then this lever by the link L imparts a transverse slidingmotion to the bar K, so that the beveled end K travels under thefriction-roller 1, whereby the slide I and link H by their own weightmove downward to swing the hook F into the lowermost position and intoengagement with the keeper Or, as shown in Figs. 4 and 5, to lock thecarriage as soon as it is stopped and prevent rebounding of the same, aspreviously mentioned.

When the lever D has been thrown to its former position and the lever Eswung to the position shown in Fig. 2, the starting mechanism for thecarriage will be thrown into active position, and simultaneouslytherewith through the medium of the link L a sliding motion is impartedto the bar K, so that the beveled end K thereof acting on thefrictionroller 1 causes an upward sliding of the slide 1 and link H toswing the hook F upward out of engagement with the keeper G to unlockthe carriage. The hook F remains in the inactive position describedduring the travel of the carriage and until the lever D is thrown overagain to stop the carriage, as previously described.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. A spinning-mule provided with a lockingdevice for automatically holding the carriage against rebounding whenstopped, the said locking device being automatically controlled from thestopping device of the carriage.

2. A spinning-mule provided with a hook mounted to swing on thecarriage, means controlled from the stopping device of the carriage foroperating the hook, and a fixed keeper at the head-stock of the machine,adapted to be engaged by the said hook.

3. Aspinning-mule provided with a locking device for automaticallyholding the carriage against rebounding when the latter stops, saidlocking device comprising a fixed keeper near the head-stock, a hookmounted to swing on the carriage, aslide connected with the hook,

and mechanism for operating the slide from the stopping device for thecarriage.

4. A spinning-mule provided with a locking device for automaticallyholding the carriage against rebounding, said locking device comprisinga fixed keeper near the head-stock, a hook mounted to swing on thecarriage, and mechanism connecting the said hook with the stoppingdevice for the carriage, the said mechanism consisting of a slideconnected with the free end of the said hook, a bar having a bevelededge, adapted to engage the said slide, to raiseand lower the same and alink connecting the said bar with a movable part of the stopping devicefor the carriage.

5. In a spinning-mule, the combination with I the carriage, and apivoted lever constituting a part of the stopping device for thecarriage, of a pivoted hook carried by the carriage, a slide on thecarriage and pivotally connected with the hook, a sliding bar having abeveled end adapted to engage the slide to raise the same, the slidefalling by gravity when released, a link connecting the bar with thepivoted lever, and a fixed keeper near the headstock and with which thehook is adapted to engage.

6. In aspinning-mule, the combination with a carriage, and a pivotedlever constituting a part of the stopping device for the carriage, of apivoted hook on the carriage, a slide pivotally connected with the hook,asliding bar pivotally connected with the said lever and engaging theslide to raise the same, the slide falling by gravity, when released,and a fixed keeper near the head-stock and with which the hook isadapted to engage.

7. In aspinning-mule, the combination with .a carriage, and a movablemember constituting a part of the stopping device for the carriage, of apivoted hook on the carriage, mechanism for operating the hook from thesaid movable member, and a fixed keeper near the head-stock and withwhich the hook is adapted to engage.

In testimony whereof We have signed our names to this specification inthe presence of two subscribing witnesses.
